From the event page:
”Britain, France and the US are committing to another disastrous military intervention. Apart from the inevitable casualties, any attack on Syria can only inflame an already disastrous civil war and would risk pulling in regional powers further.

Most people in this country have learnt from the disasters of Iraq, Afghanistan and Libya. According to a Telegraph poll today only 9% of British people support an attack. Our politicians however have learnt nothing.

We need the maximum level of protests to stop them plunging us in to yet another catastrophic war.
